The continuous deterioration of ore quality in regard to grade, hardness, finer particle sizes and the increase of metallurgical complexities have made modern process mineralogy an integral part.
The major flotation feed sulphide mineralogy reported by simwaka et al. are pyrrhotite (more than 24% of the mass contribution), followed by chalcopyrite (2%), pentlandite (1.7%) and pyrite.
The process is energy intensive with power consumption of roughly 20 to 30 mw and feed throughputs of 2,500 to 3,000 t/hr. process variables are mill loads, motor torque and power, plus pressures and flow rates. the ground product is specified in terms of.

The production schedule achieves the target process plant throughput rates both during ramp-up and during steady state operations of 3.0 mt/y to 3.2 mt/y (peak), it said. the copper recovery plant and associated service facilities will process run of mine (rom) ore delivered to.
The t3 process flowsheet incorporates the following major process operations: • primary crushing • coarse ore stockpile with reclaim system • open circuit semi-autogenous grinding (“sag”) with ball mill operating in closed circuit • rougher flotation • rougher concentrate regrind mill • cleaner flotation • cleaner scavenger.
Thus, before the flotation, process of sulfurization was made in order to change the ore structure and surface properties (9, 10 and 11). the sulfurized samples were subjected to flotation and the results were evaluated. 2. materials and method 2.1. materials the copper ore containing gold and silver used in this study was obtained.
We claim 1. in the concentration of ores by subjecting an aqueous slurry of the ore to froth flotation in the presence of a collector and a frother, the improvement of using an effective amount as a frothing agent of a polyoxypropylene adduct of glycerine, hexanetriol, diglycerol, sorbitol, pentaerythritol, a monosaccharide, a disaccharide or mixture thereof having at least 5 oxypropylene.
